Next to the colours I also like the DOF (depth of field) you chose, thus totally blurring out the background (which is green. Nice!!!!) and the fact that these leaves are backlit, i.e. the light shines right through them from behind. And I like the fact that you went up so close and captured a PART of the autumn foliage only.

And if you want to put up more than one pic, you just put up the first [IMG ]-wrapped link, then push spaces (the back button) twice and put up the next.
